I have known that having a good fitting bullet matters. However I just learned how to check if you have the correct size bullet in a revolver by placing the cast bullet in the throat end of the cylinder and see if you can push it through. And if you can do it with a little force then you are probably good to go as it is roughly .001-.002" bigger than the throat of the cylinder and that's what you want.
Well I went and grabbed my Ruger SP101 and some bullets I casted and gave it a go. The bullets I used were tumble lubed and resized. When placing them in the throat of the cylinder it took some force for me to get them to go through. I really don't know how much force but it took some. I pushed them through with the back side of a ball point pen. How much force should I be using to know its not to tight? I didn't need to use a mallet or anything just a good grip on the pen and applied good pressure till it pope through. I even tried it with the ones I powdercoated and it felt the same as the tumbled lubed ones. I dont know the exact size of the bullets or the resizing die I used as they are at a buddys house right now.
